Abstract: A process for producing ethylene and at least one of butanol and an alkyl tert-butyl ether from field butane includes separating the field butane into an n-butane stream and an isobutane stream; cracking the n-butane stream to obtain a cracked product stream comprising n-butane, 1-butene, 2-butene, butadienes, or a combination comprising at least one of the foregoing; and at least one of the following: (1) separating the cracked product stream to obtain a butane stream and a butene stream, and reacting the butene stream with water to obtain a fuel additive comprising butanol, and (2) dehydrogenating the isobutane stream in a dehydrogenation unit to form an isobutene stream and reacting the isobutene stream with an aliphatic alcohol to produce an alkyl tert-butyl ether.

Abstract: A method of producing a fuel additive includes: passing a raffinate stream comprising C4 hydrocarbons through a hydrogenation unit, forming a first process stream; passing the first process stream through an extractive distillation unit, forming a C4 olefin stream; passing the C4 olefin stream through a stripper column, forming a purified C4 olefin stream; and forming the fuel additive by passing the purified C4 olefin stream through a hydration unit.
